| 摘 要： | 文中研究了一种火试金富集测定锌阳极泥中银含量的方法.以铅富集银, 形成铅扣, 将铅扣在适当的温度下进行灰吹除铅, 灰吹时铅氧化成氧化铅渗透于多孔的灰皿中, 从而除去铅及杂质元素, 银不被氧化而留在灰皿中形成银粒, 用称量法得到银粒质量, 银粒质量减去氧化铅空白中银的质量即得银的含量.该方法不需要进行二次试金, 工作效率高、成本低、结果准确、重现性好, 能够快速、准确指导生产, 适合于现代化企业生产.本方法适用于锌阳极泥中银含量50~1000 g/t的测定.

| Abstract: | In this paper, a method for determination of silver content in zinc anode mud by concentration of fire test gold is studied.Rich in silver by lead, form a lead buckle, to remove lead at suitable temperatures, when ash blows, lead oxidizes to lead oxide and penetrates a porous ash dish to remove lead and impurities, Silver is not oxidized and remains in the ash dish to form silver particles.Silver grain quality obtained by weighing method, Silver grain mass minus lead oxide blank silver mass is the amount of silver.The method does not require a second trial and has high efficiency, low cost, accurate results and good reproducibility, ability to direct production quickly and accurately, Suitable for modern enterprise production, This method can be used for the determination of the silver content in zinc anode mud 50 ~ 1000 g/t. |
